Another tournament means another opportunity for us to geek out with spreadsheets! If you follow our blog, you may have seen our previous models: Basketball, Soccer, Football. Now we are back with the Women’s Soccer Championship Predictions! Speaking of our previous models, our track record isn’t bad – our Basketball template correctly predicted Virginia as the winner! Read on to better understand how the tool was built and how to use it.

Before going over the details, it is useful to understand how the Women's Championship is structured, since this will help understand the model:
Building and Adjusting your Bracket
The model has three main components: Group Stage Predictions, Group Stage Adjustments, and Playoff Predictions. The model is pre-filled with data and ready to go, but you can change parameters if you want to customize a team’s performance or override specific match results in the Group Stage matches.
Note: Because the model looks at past performance and runs different possible outcomes using a Poisson distribution, it recalculates every time you modify values, tap F9, or choose Formulas – Calculate Now.
For the Group Stage portion of the championship, you can do one of two adjustments:
Once you have made your adjustments for the Group Stage, you can see the outcome through the Round of 16, Quarter Finals, Semi Finals and Finals in the “Playoff Predictions” tab:
About the Prediction Model
Last year we built the 2018 prediction model, so instead of re-inventing the wheel, we leveraged this work and updated the input with the international women’s soccer ranking and historic data. We also adjusted the model to account for differences in the Women’s version: fewer teams (24 instead of 32), fewer groups (6 instead of 8), and a different logic to pair teams for the Round of 16. If you want all the details of how the model was built, and the concepts behind it, check this blog post.
Concerning data, for the men’s championship we used a consolidated dataset that included all games played over the last 146 years. Unfortunately, international women soccer is much younger than its men counterpart, and there is less data available. However, we were able to consolidate game results from several sources:
